Chapter 24      Configuring Routing and Delivery Features
  Configuring Mail Gateways for all Hosted Domains Using Virtual Gateway™ Technology
Note
A listener checks the information in the 
altsrchost
 table and directs the email to a particular interface 
after checking the masquerading information and before message filters are checked. 
Use these subcommands within the 
altsrchost
 command to create mappings in the Virtual Gateways 
via the CLI:
Importing an altsrchost File
Like the HAT, the RAT, 
smtproutes
, and masquerading and alias tables, you can modify 
altsrchost
 
entries by exporting and importing a file. 
Procedure 
Step 1
Use the 
export
 subcommand of the 
altsrchost
 command to export the existing entries to a file (whose 
name you specify). 
Step 2
Outside of the CLI, get the file. (See 
information.) 
Step 3
With a text editor, create new entries in the file. The order that rules appear in the 
altsrchost
 table is 
important. 
Step 4
Save the file and place it in the “altsrchost” directory for the interface so that it can be imported. (See 
 for more information.) 
Step 5
Use the 
import
 subcommand of 
altsrchost
 to import the edited file. 
altsrchost Limits
You can define up to 1,000 
altsrchost
 entries.
